In general, the coil subjected to annealing is subjected to a polishing line to remove defects on the surface of the strip, which is then sent to the next process, which is performed by strip grinders arranged along the line. The generated swarf is sent to the swarf processing unit through a chute installed on the bottom of the grinder.

The swarf generated during strip polishing is a mixture of coolant oil used for polishing and fine chips polished from the strip, and then aggregated together into a cottony form. The swarf sent to the swarf processing unit is screened and filtered into oil and fine chips. It can be separated and reused.

The frame 84 connecting the shaft 80 and the removal bar 82 is caught by the stopper 86 so that rotation is performed. Stopped so that the end of the removal bar 82 can be located exactly inside the next push rod.

In this way, all the swarf conveyed by the conveyor 114 is dropped to the swab receiving 10 without leaving by the removal bar 82.

When the swarf transported to the conveyor 114 falls into the swab receiving 10, it is transferred to the feed pipe 50 by the rotating screw 12 that is rotated. The wheat plate 16 moves forward to push out the lumped swarf.

That is, the light emitted from the light emitting sensor 30 on the side of the swab receiving 10 toward the input tube 50 is reflected by the reflecting plate 34 installed on the side of the receiving swab 10 and sensed by the light receiving sensor 32. When the lumped swap is transported, the light of the light emitting sensor 30 is obscured, and the light receiving sensor 32 detects the blockage of the light by the swap.

Therefore, the controller 70 receiving the detection signal from the light receiving sensor 32 pushes the driving plate 20 and pushes the plate 16 connected to the piston rod to inject the lump swab on the feeding tube 50 side. It will be pushed out of the tube (50).

In the table 22 in which the plate 16 is installed, the roller 26 at the tip rolls along the upper end of the swab 10. As the driving cylinder 20 extends and extends, the upper plate 26 is disposed along the upper end of the swab 10. The sliding plate 16 is allowed to advance.

In this process, the lump or agglomerated swap is crushed by the mill 16 and the transfer screw 12 is decomposed to a suitable size.

Here, while the plate 16 is in progress, the swarf continues to fall through the conveyor 114 to the swab receiving 10, and the dropped swarf falls on the table 22 connected to the plate 16 and accumulates.

The swarf accumulated on the table 22 is caught by the blocking plate 28 on the feeding tube 50 side as the driving cylinder 20 is contracted again and the table 22 returns to the feeding tube 50. Fell on).

That is, the blocking plate 28 standing on the upper part of the table 22 is fixed to the swab receiving plate 10, so that the swarf traveling together with the table 22 is caught by the blocking plate 28 so that all of the receiving plate 10 can be replaced. Will fall.

The dropped swap is conveyed by the transfer screw 12 to be introduced into the injection tube 50.

On the other hand, the swarf dropped into the inlet tube 50 through the inlet 40 of the swab receiving 10 is crushed finely by the cross-shaped iron core 54 installed in the inlet tube 50 is introduced into the centrifuge 120. .

As shown in FIG. 4, as the driving motor 58 operates, two rotary rods 52 connected to the sprocket wheel 56 and the chain 60 rotate in a clockwise direction, and are installed in the rotary rod 52. The cross-shaped iron cores 54 alternately cross each other and rotate in the same direction.

Therefore, the swarf introduced through the inlet 40 falls over the cross-shaped iron core 54 installed in the rotary rod 52 on the left side, and moves to the iron core 54 crossing area between the rotary rods 52 according to the rotation of the iron core 54. Will be moved.

In this intersection area, the iron core 54 on the left side rotates down and the iron core 54 on the right side rotates up, so that the swap between the left iron core 54 and the right iron core 54 intersects the core core 54. Will be broken up into pieces.
